Re: [Amforth] Soft Serial Port
Jan, > What do you mean with “and a small sck period” The smaller the SCK period the faster the programmer tries to program the target mcu. There are limits and not all programmers/software support user altering of the SCK period. I think you mentioned you use a Pololu programmer so this link might help. https://www.pololu.com/docs/0J67/5.7 Best wishes, Tristan ___ Amforth-devel mailing list for http://amforth.sf.net/ Amforth-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/amforth-devel

Is this by the structure of the Mega? Not an answer to your question, but it seemed to take longer than I wished! If you load atmega2560.frt, which is twice the size of atmega328p.frt, it will take longer. I ended up deciding what my base set of .frt files would be, loading them via amshell once, then used avrdude to write an image of the flash and eeprom to my pc. I would then write these instead to the atmega2560 when I did something such that the atmega2560 was no longer talking to me. Despite the substantial size of the files, it seemed quicker to burn them with avrdude (and a small sck period) than burn atmega2560.hex, atmega2560.eep.hex, and then load the base set of .frt with amshell.

Re: [Amforth] Soft Serial Port
Tristan, Loading my Mega with forth was a succes. After loading my fix amount of screens, witch are the same as on the Arduino it took significant more time to save and load the new image. Is this by the structure of the Mega? So far no finding thats worry my. It runs as it should! Great project from your side. Will maybe a fix item into the repository of amforth.

Re: [Amforth] Soft Serial Port
Jan, A number of things. The hex file you have found may not be one for the Arduino Mega2560. If I remember correctly, the distribution has an appl folder for the atmega2561 and the configuration assembler file https://sourceforge.net/p/amforth/code/HEAD/tree/trunk/appl/atmega2561/atmega256.asm suggests that it was built for an ATmega2561 with an 14.745600MHz crystal and uart1 hosting the AmForth interpreter. I adjusted the AmForth make system (on OSX) to build a custom hex file for the Arduino Mega2560 which uses ATmega2560 chip and a 16MHz crystal. I also put the AmForth interpreter on uart0. The AmForth build system is one of its many strengths, though getting it to work on OS X does require a few extra steps. I used these fuse values for my Arduino Mega2560 > avrdude: safemode: Fuses OK (E:FF, H:99, L:CE) Finally, what hex programmer you use may be important with the Mega2560. I used an avrisp2 compatible programmer and had no problems. However, I can confirm that my usbtiny programmer couldn't program my Mega2560 successfully.

Re: [Amforth] Soft Serial Port
Tristan, Found the hex files for the Mega, but don’t found the fuse values. Please can you help me out with these.

In an attempt to cross this off my would-like-todo list, I now have AmForth 6.8[1] on an Arduino Mega 2560 with the interpreter hosted on usart0 and second working usart, usart1 configured for 9600 8N1. Incoming and outgoing bytes are buffered, with those buffers being serviced by the usart1 RX and UDRE interrupts. I've been using multitask.frt to create background tasks to process the buffered RX stream and then act on it in some way. For devices that send small amounts of serial data, slowly, every so often, it might be a usable approach. Best wishes, Tristan [1] I think the prompt still says 6.7 (via env-forthversion.asm). ___ Amforth-devel mailing list for http://amforth.sf.net/ Amforth-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/amforth-devel

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 Forth kernel for it. The AmForth package comes with a hex file for the old Arduino Mega board (fitted with a ATmega1280) and that might not be fully compatible with the ATmega2560...

Re: [Amforth] Soft Serial Port
Hi Jan, Not as far as I know. However, the mailing list archive https://sourceforge.net/p/amforth/mailman/amforth-devel/ is worth searching (bitbang) and there are some messages relating to your particular question. It would certainly be a nice feature to have, perhaps along with being able to access a second hardware uart from within AmForth. The latter has been on my would-like-todo list for a while. If anyone has achieved this I would be grateful for any pointers.
