Re: [Amforth] bitnames.frt issue

Re: [Amforth] AVR8 build questions

Hello Tristan, If you want a flexible multi-purpose board perhaps you want to include a DAC, and a high resolution ADC. Semiconductor relays for switching loads. It may also be useful to have extra UARTs, but for this you might prefer to use the 2560 instead of the 1284. If you want to

Re: [Amforth] Coolterm on the Mac

Jan, By default CoolTerm starts up in the Raw mode, in which each character is sent as it is entered on the keyboard. I presume when you hit the delete key it will be sent as a non-printable ASCII code. If you set CoolTerm to the Line mode (under Options / Terminal) you can then enter and

Re: [Amforth] Setting of the fuses Arduino Ono

Jan, For the Arduino Uno we have been using the following command string successfully: avrdude -p m328p -c avrispmkII -P usb -U efuse:w:0xFF:m -U hfuse:w:0xD9:m -U lfuse:w:0xFF:m -U flash:w:uno.hex:i -U eeprom:w:uno.eep.hex:i Thus argument for efuse is set to FF instead of 05. The short

Re: [Amforth] A good editor/terminal for MacOSX

Hello, We have been using CoolTerm on the Mac. When you send files with it you just have to make sure to add some delays in the preferences settings of CoolTerm so that Forth does not get overwhelmed. Peter Hauser > On 15 Oct 2018, at 14:56, Jan Kromhout via Amforth-devel > wrote: > >

Re: [Amforth] Coolterm as terminal

Jan, With CoolTerm it is not possible to use the “include” mechanism. However, there is a terminal program (shell) specifically written in Python for use with FlashForth (flashforth.com). This most likely also works with AmForth and most likely can handle “include”. I once tried but could not

Re: [Amforth] How to make a Full system

Jan, I do not think there is an overview regarding the sequence. In any case, you probably do not just want to load everything, only what you need for your project. As far as I know AVRDude lets you read back the memory contents and it should be possible in this way to easily clone a

Re: [Amforth] Arduino Nano

Jan, Yes, we used the same fuse settings for the Arduino Nano as for the Arduino Uno. They both use the same AVR microcontroller and the circuitry (as far as I know is identical), it is just the form factor which is different. We prefer to use the Nano as we can plug that into the printed

Re: [Amforth] Flashing AmForth to Arduino Leonardo

Jan, Have a look at this: https://github.com/arduino/Arduino/pull/5182 At some stage AVRDude changed the way it reads back the unused fuse bits and thus the e-fuse parameter in the command line had to be adjusted. I had this problem with the

Re: [Amforth] Soft Serial Port

Jan and Tristan, If you want hardware serial you cannot really use the Arduino Uno as the ATmega328 microcontroller only has one UART, which is used by Forth for its communication. The ATmega2560 on the current Arduino Mega board has 2 spare UARTs. However, one might have to first build the

Re: [Amforth] Need some help with the SPI

Jan, Can I suggest that in order to get to grips with it, rather than starting with the Arduino example, study the data book for the microcontroller to learn how SPI is controlled with the related registers, and then study the SPI words provided with the AmForth package. C/C++/Arduino

Re: [Amforth] Need some help with the SPI

Jan, You can also use the following words to avoid c!@spi, which is missing from the preassembled package for the Arduino: \ send a byte, ignore received byte : c!spi ( c -- ) SPDR c! ( c addr -- ) ; \ receive a byte, send a dummy one : c@spi ( -- c) 0 SPDR c! 1 ms SPDR c@ ; SPDR

Re: [Amforth] Need some help with the SPI

Dear Jan, spi.setmode is used to set one of the 4 SPI modes 0, 1, 2, or 3, e.g. "1 spi.setmode". The mode to use depends on the device you want to connect to, and you will find it in the datasheet (perhaps not explicitely stated, but the necessary information will be there). Most common is

Re: [Amforth] how to use bitmask:

Jan, For a general idea on masks you might want to consult p. 92 of "Starting Forth". If I remember correctly "bitmask:" will create a bitmask, but not do the bit-setting for you. One has to write to the registers to do that (not sure anymore if it is just "c!" or a special version of store
