I purchased a Portenta H7 and am looking to use it for a project. I ran into a problem with the naming/pinout lineup. If I look at the pinout page, I see that there are the following UARTs: 1,4, 6, and 8. pins: https://github.com/micropython/micropython/blob/master/ports/stm32/boards/ARDUINO_PORTENT...

Ah didn't realize there was a built in W5500 with an RPi. In any case, I definitely planned on the W5500 for the physical ethernet layer. Was more curious if anyone had thoughts on the software side of things

Hi all, EtherNet/IP is becoming a bigger and bigger part of industrial communications. I thought it would be really neat to use an RPi 2040 to act as as a gateway to handle communications and interface with another board over UART. The idea being that one core would handle the EIP side of things and...

As a little update in case anyone searches for the SC16IS740 in the future. I am getting reading and writing registers at this point but it is intermittent. Seems like I am going to have to break down and get a logic analyzer. Meanwhile I am doing the following (basically what I wrote above): LCR_re...

Hi all, I am back with a simple question. I am using a pyboard to communicate with a six devices over UART. Of course it only has five UARTs available so I am using a breakout board with a SC16IS740 SPI to UART converter. https://www.digikey.com/en/products/detail/mikroelektronika/MIKROE-3349/996030...

Robert, please update if you end up doing this. I am unexpectedly not going to work on this for a couple of weeks. So if you tackle it before I get to this, I'd love to utilize your work. Though doing this myself would be a good learning experience.

Raul, Thanks so much for providing this! This should work for me. I did some poking around for current drivers out there but couldn't find any so this fantastic. I'd still be interested in implementing DMA, but I realize I am asking for a lot of support. I am planning on doing quite a bit with my co...

Hello all, I am looking to setup a Pyboard 1.1 to read data from multiple ADC channels using an ADS1118. I'd like to read a continuous data stream from multiple channels on the ADC. To do this, I believe I need to setup DMA to write data into buffers. Here is the ADS1118 datasheet: https://www.ti.co...
