Hi! I'm trying to send some data (or string or anything) from the computer to a Nucleo-64 board, with no luck at all. I can easily retarget the printf and is working perfectly, but it is receiving nothing from the computer. Do anyone have any suggestion? In the specific, I tried with Nucleo-L432, Nucleo-L476, 32L476-Eval.

Yes, I know, there is a lots of ready and available OSes for STM32 Cortex-M3, -M4 and sometimes -M7. Yes, I know, there is a support of STM32 chips in mainline kernel. Yes, I heard about Emcraft.   Yes, I got my own design of STM32F746 board, loosely based on STM32F7-Discovery: 64 megabytes of 32 bit wide memory (running on maximum available… (Show more)

STM32F437 processor I have no experience using the stm32 timers with DMA so I wish to solicit suggestions before banging my head against the wall.   I have set up a counter using an ISR to count pulses (RPM) and it works quite well for low speed and extremely low speeds. If the speed is real slow the timer overflows and triggers an interrupt. I… (Show more)

Good morning,   I have a problem with the declaration of an array. if I declare these two arrays before the main I have no compilation/linking problem uint16_t buffer [48000]; uint16_t buffer2 [48000]; but if I try to declare only one array of 49000 elements uint16_t buffer [49000]; I get this error Error: L6406E: No space in execution regions… (Show more)

Can not set the input frequency value of quartz LSE/HSE - after entering the frequency value and loss of the input focus, the frequency is divided by 1000. The division is repeated if you return and remove the input focus again. As a result, an error occurs with respect to the frequency value. In version 4.19 everything was fine. How to fix?

When an SPI in SLAVE is clocked continuously (with NSS active) and DR is *not* written upon every TXE set, there are several possible scenarios for MOSI behaviour after the last explicitly written data bit is transmitted: MOSI is set permanently at a predetermined level (0 or 1) MOSI remains permanenlty at the last transmitted bit's level MOSI… (Show more)

I tried to upgrade my working project, ad the result is project unusable !   The SD part is impossible to use, missing definitions, missing functions and others problem.   Its possible to downgrade cubemx and return to previous version ?

Hello, I need to configure the parameters of timer TIM6 inside the STM32F769 to trigger the DAC output. The triggering time is variable and must be set depending on some parameters sent to the MCU from a PC. The minimum triggering time is 2 us and the maximum is 500 s. I am wondering whether setting the TIM6 as DAC trigger is the best way to… (Show more)

I ultimately need "instant on" ADC conversions.  For instance, when a timing gate goes high, I need to start taking ADC values immediately (the signal is only 100us wide),  The problem I'm running into is the lag: firing up the ADC in DMA mode from a "cold start" takes 50+ usec to start getting values.  I tried leaving the ADC/DMA running, and… (Show more)
