FAQ: GPIO vs IO Expander.
Hello world :-) There are platform specific drivers for GPIO and the IO Expander driver. Which one should I use? What are the advantages of using Arch/Board hardware GPIO driver versus IO Expander? What are the drawbacks? Does IO Expander provide custom IRQ callbacks to GPIO input? Which one would provide platform portability (that is should work on a real hardware of different sort and/or sim)? How to interact with GPIO on the Simulator? Is there a client application that would allow easy control of GPIO inside the Simulator (i.e. unix/tcp sockets)? Is something like Verilog test bench possible? Any hints welcome :-) Tomek -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info

USB HID and/or Bluetooth HID ? :-) https://www.usb.org/hid https://www.bluetooth.com/specifications/specs/human-interface-device-profile-1-1-1/ There is an example app in NuttX Apps for USB HID Keyboard.. but I did not use it myself.. mouse works similar way :-) https://github.com/apache/nuttx-apps/tree/master/examples/hidkbd > Explaining the issue: I have an ESP32 board with LCD and touchscreen > and I want to create a low cost alternative to Elgato StreamDeck, but > unfortunately ESP32 doesn't have USB. Is Bluetooth HID an option? That would require no external hardware / modifications, just a standard Bluetooth HID implementation that should work out of the box on all platforms with no additional custom drivers. Also you can leverage WiFi block and transport HID over TCP/IP somehow and that would provide even broader access but that would require some driver/software/daemon on the target machine. As for USB, in a perfect situation you would have USB Device block in the MCU and you can create set of logical devices each for a given function (one physical USB connection can host many logical devices for instance mouse, keyboard, uart/cdc, mass storage, etc) that you describe with a descriptors and those tell what endpoints are read/write sink/sources of a function data (kind of similar to BLE). One physical device can have several configurations that change on the fly so you can switch logical functions as you wish. But you need a USB Device block for that. I miss that part in ESP32 too :-( The most common solution in that situation is to use MCU with USB Device or external chip that would enable USB HID functionality but that may cost similar to cheapest MCU with USB Device block. The ESP32-C3 or ESP32-C6 seems to have some sort of USB-JTAG/UART block. I did not play with this one yet.. but for compatibility reasons it may use USB HID transport for UART and JTAG.. if so maybe it would be possible to cheat the MCU block somehow in order to provide USB HID mouse/keyboard functionality :-P > So I think I need something similar to Microsoft VHF (bad name > Microsoft, shame on you) > https://learn.microsoft.com/en-us/windows-hardware/drivers/hid/virtual-hid-framework--vhf- > > AFAIK Linux doesn't support Virtual HID (at least not yet). > > The best option I found was netstick: https://github.com/moslevin/netstick I would go for Bluetooth HID (widely adopted standard but short range), or the HID over WiFi using above projects (custom part on the target machine but more versatile) :-) Good luck and have fun! :-) -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info

STM32 SmartCard mode happening right now
HI, No idea why this message did not make it through. Resending with small updates. Hi, it is time! I am, right now, starting to implement the smart card mode for STM32 USART, starting with STM32H7, this will be portable to other STM32 chips I guess. The UART mode will just configure the uart for smartcard shenanigans, eg, put it in working order for this mode. Smart card contact protocols (T=0, T=1) will go into a user space app that manages readers, similar to pcsclite daemon in linux. So the smart card mode of the stm32 usarts is just an activation of the proper registers, that will : -wire the hardware as expected: enable the clock output, define one single full duplex IO line -reconfigure the uart character framing, including parity generation and detection, which is a fundamental mechanism, required for protocol compliance testing. The exchanges will still be made with the read() and write() primitives (protocol is a kind of IPC), so I am expecting to add just one IOCTL, like is done for LIN, single wire, and 485: +#define TIOCSSMARTCARD _TIOC(0x0038) /* Set Smart Card mode */ +#define TIOCGSMARTCARD _TIOC(0x0039) /* Get Smart Card mode */ The parameter given to the IOCTL must be able to: -ENABLE smart card mode with a bool parameter to enable or disable, default disabled -START or STOP the clock signal -Define the communication convention -Define the communication speed in terms of ETU (clock pulses per bit, which is different from the baud rate and the industry standard way to define smart card comm speeds). This need to be modifiable, the speed is negotiated dynamically at card insertion. -Define the character guard time, which is a delay between transmitted characters. This will return a ENOTTY error if a particular uart does not support Smart Card mode. The goal is to facilitate the upstreaming of this feature. I know smart cards are unusual and quite niche, you can ask me as many questions as needed to understand smart card context, behaviour, and habits. Does anyone have suggestion about this uart mode?

STM32 SmartCard mode happening right now!
Hi, it is time! I am, right now, starting to implement the smart card mode for STM32 USART, starting with STM32H7, this will be portable to other STM32 chips I guess. The UART mode will just configure the uart for smartcard shenanigans, eg, put it in working order for this mode.

So the smart card mode of the stm32 usarts is just an activation of the proper registers, that will : -wire the hardware as expected: enable the clock output, define one single full duplex IO line -reconfigure the uart character framing, including parity generation and detection, which is a fundamental mechanism, required for protocol compliance testing. The exchanges will still be made with the read() and write() primitives (protocol is a kind of IPC), so I am expecting to add just a few IOCTLs: -ENABLE smart card mode with a bool parameter to enable or disable, default disabled -START or STOP the clock signal (if possible, I did not dive in the RM yet) -Define the communication speed in terms of ETU (clock pulses per bit, which is different from the baud rate and the industry standard way to define smart card comm speeds). This need to be modifiable, the speed is negotiated dynamically at card insertion. This will return a ENOTTY error if a particular uart does not support Smart Card mode. However, to be future proof, another way is possible. USB CCID smart card readers are also a thing. In pcsclite (linux), these are managed via libusb from userspace. But we can do something special in NuttX, like defining a smart card "lower half" that can be implemented by both the stm32 uart in smart card mode, or by the future usb ccid driver. I do not plan to *port* the full pcsclite, but I will do something that tend to be compatible, while being much smaller. The great question is then how to manage the "upper half" of such drivers. If it was just me, it would be a character device, that would have IOCTLs to enumerate lower halves (eg card readers) so a user space app can dispatch commands to multiple readers. But I know NuttX despise character devices. So, I am going to need some inspiration here. Sockets do not seem appropriate to how things work in the smart card world, I can tell that from 13 years of professional experience :) If NuttX has a libusb-like protocol now or later, then we dont need to be concerned by this lower half and char dev, this can all happen in the management daemon. There are also modular card readers that use plain old serial protocols, these would also be handled from the user space daemon via specific drivers. So, this is the correct time to define this in a way that please everyone and will be useful for a long time. We need compromises between imperative needs of this mode and the NuttX way of doing things. The goal is to facilitate the upstreaming of this feature. I know smart cards are unusual and quite niche, you can ask me as many questions as needed to understand smart card context, behaviour, and habits. Thank you for your reading and comments Sebastien

How to export HID events from NuttX to Linux (or others Desktop OS) ?
Hi Everyone, (sending again with right subject) Since many here probably faced similar challenge in the past let me ask: How to export HID buttons events from NuttX to Linux? Explaining the issue: I have an ESP32 board with LCD and touchscreen and I want to create a low cost alternative to Elgato StreamDeck, but unfortunately ESP32 doesn't have USB. So I think I need something similar to Microsoft VHF (bad name Microsoft, shame on you) https://learn.microsoft.com/en-us/windows-hardware/drivers/hid/virtual-hid-framework--vhf- AFAIK Linux doesn't support Virtual HID (at least not yet).

Thank you Alan for this great idea and inviting me to the Hackert's admin group :-) I have updated a bit the front page hope its readable and well aligned with other organizations.. we will add more sections as content shows up :-) https://www.hackster.io/nuttx I have question to Hackster team Jinger: there is a lot of various projects using NuttX at Hackster already. Is it possible to create "NuttX RTOS" tag to add them somehow to the list of our Hub's projects or add them by hand? What would you recommend?
