Re: STM Nucleo-32 board - I2C functionality

Hi Stewart, You are right, there is a mistake regarding pin definitions in the file boards/arm/stm32l4/nucleo-l432kc/src/stm32_ina226.c. I tried to fix these pin definitions on PR #10753 but I can't test them. Are you able to test it? Thanks Daniel Pereira de Carvalho Em qua., 20 de set. de

Get control of NSH serial port?

Hi guys, I am writing a program for a board that has only one serial port available, the one used by NSH. My application needs to use this port for MODBUS so, my application needs to take control of the serial port and give it back to NSH when execution is done. Is this possible? If yes, how can

Is SmartFS limited to 16M memories

Hi guys, I am trying to use the memory W25Q256JVEIQ, with SMARTS FS. To do it I added the support for this memory in "drivers/mtd/w25.c". I just added the code below *..#define W25_JEDEC_CAPACITY_256MBIT 0x19 /* 8192x4096 = 256Mbit memory capacity */../* 256M-bit / 32M-byte

dummy folders in nuttx tree

Hi guys, Looking at nuttx folders I saw two folders called "dummy", specifically nuttx/dummy and nuttx/drivers/dummy. The last one is referenced by the symbolic link nuttx/drivers/platform. What is the reason for this? Thanks Daniel Pereira de Carvalho

STM32G4 analog camparators

Hi, I'm trying to use the analog comparators of the nucleo-g431kb board. As a reference I'm using the implementation and pin definition of the nucleo-f334r8 board. Looking at RM0364 Reference manual section *15.3.2 COMP pins and internal signals* there is the following *"The I/Os used as

CONFIG_RAM_SIZE variable

Hi, I've been working on NuttX support for nucleo-g431kb. This work is based on nucleo-g431rb, which is pretty similar, both boards have the same amount of flash and ram memory (128K flash and 32K RAM). Looking at defconfig files I noted that the variable CONFIG_RAM_SIZE is setted to 22528 (22K

I've just tested the external board build following these simple steps. 1 - Clone nuttx and nuttx-apps on base dir 2 - Created a new dir called board $ mkir board $ cd board 3 - Copied nucleo-l432kc board directory $ cp -r ../nuttx/boards/arm/stm32l4/nucleo-l432kc/ ./ 4 - Configure

Re: select()/pselect() function

Hi Greg, Thanks for the answer. I don't understand why I should use 1 instead of fs + 1. The documentation says "nfds This argument should be set to the highest-numbered file descriptor in any of the three sets, plus 1. " In the portserial.c nfds was set to fd + 1 Daniel Pereira de Carvalho

Re: NuttX and continuous ADC conversion

Maybe you could propose a modification on ADC upper-half driver to enable overwriting. So, if the FIFO is full the oldest value is replaced by the new one. This could be an option on the config system. At this moment I am working on STM32L4 ADC driver. I am implementing the low level operations,

Re: NuttX and continuous ADC conversion

If I understand well, you want to put the ADC to continuously sample an input at some sampling rate.The ADC ring buffer depth will be set to 1 and should store the value of the last sample. Is that correct? If yes I think that is not possible because adc_receive() will refuse new data if FIFO is
