Arduino for STM32

I got one of those years ago. Did a lot of my initial conceptual work on it. It works great with a HAL based Arduino like the stm official core. The one limitation is that if one wants to add an ethernet PHY, there are some hoops one has to jump through, like removing the MEMS gyro and having to dea...

From the muddled discussion in the other groups this is the wrong approach due to the way DMA works. The system expects to fit 9 bits into two bytes, but the registers are 4 bytes. Timing is what is the critical path here. That one has in effect 1 frame between the 9 bit data and the 8 bit data. So ...

I have a pipe organ controller project that I inherited that mixes 9 and and 8 bit data. It was originally written for 8051. The coms are half duplex RS485. The protocol is sort of a corruption of MIDI. There are 128 bits on each input board connected to a shift register for 16 bytes of storage per ...

I was having almost the same exact problem. I just managed to port some Atmel 32UC3 code that uses UDP. This code floods the local net with UDP packets. A few seconds generates 100s of 1K packets. (a minute is about 13MB in the wireshark pcap dump.) There is not a lot online about lwip or the low le...

I never created an account in ST community -- to many accounts as it is

For what it is worth, I installed the tools on my laptop which runs 10.13 (High Seirra.) and do not have the issue. So I think it has something to do with the write protection.

Maybe the linker is a 32bit app? Last OSX doesn't support 32 bit app anymore. Linker is fine. Both apps are written in JAVA so the 32 bit restriction is not the issue. Sw4stm32 projects created in eclipse work fine. Older CubeMX projects which already have a linker script work fine. I have not had ...

I only have sw4stm32 on this mac. Have not tried any of the other toolchains.
The sw4stm32 is not generating the linker script

This may be a bit off subject apart from the use of C++ So I upgraded my system and everything seems to run. But I have a glich today. I wanted to create a C++ program using CubeMx 5.5.0 and sw4stm32 1.17.0. On OSX 10.15.3 (Catalina) Everything worked until the linker stage. For some reason there is...

So my tusty 2012 mac mini bit the dust. I got new 2018 version. They completly re -did it as a media device. even making it black in color, As It was a new machine I decided to go with the latest system. The internal drive is soldered in, But I have everything backed up anyway to an external disk. (...

MIDI polyphony with lots of chords really does not work for pipe organs. On the other hand it works quite well for mapping the keyboards as there are only 61 keys per manual. Ideally the output is proper pipes. The main issue is the space it takes to place a few thousand of them. Most of the stuff I...
