Hello, I'm new to working with STM32 microcontrollers and coding in C. I'm trying to send data in hexadecimal format using the FDCAN bus. However, when I check my code during debugging, I notice that the transmitted data looks different from what I ...
I am used to find the CMSIS files (especially stm32f10x.h) in the same ZIP file as the STM32F10x standard peripheral library.In my legacy project, someone used the SPL V2.0.1 together with a stm32f10x.h V3.1.0.Unfortunately, the code won't compile un...
Hello all,We're having some 'strange behaviour' when interfacing our STM32F7 to a FPGA over the FMC bus. To isolate the problems, we're looking at all the control/addr/data on the FMC bus during memory transactions. We have a very good view into ev...
Hi STM32-Community,I'm currently using an STM32L4R-MCU and was trying to set it up for standby. By using LoRa, I don't want it to keep requesting an OTAA-Command to join the network, I'm trying to use the SRAM2 Retention of my MCU in Standby-Mode. Go...
Hi everyone,I'm using the STM32F4 Discovery board to communicate with DC Power Supply Programmable ODA OPM Series using RS232.Now, I can send SCPI commands to device (OUTP ON, OUTP OFF, VOLT 10,...), but when I send some query commands, I can not rec...
So,I set my DMA at circular mode ,adc at continuous mode ,but when I debug the timing to get into HAL_ADC_ConvHalfCpltCallback(),I found the buffer is already fulled,can someone tell me what's going on?
This question does not show any research effort; it is unclear or not usefulI am pretty a newbie in display control and I am struggling with my simple application. I need to calculate some numbers on my nucleo and then display them on a screen. Since...
Hello, I have a problem with threads. All of them are of same priority, with osDelay(300), except the uartThread which has osDelay(1). Everything else is the same for all threads. I have allocated 20k of HEAP and in ioc file it says im using only 3.5...
Hello All, I am trying to write a baremetal code for ADC, to work in Continous SCAN mode. I needed help with a few bit in internal ADC peripheral in STM32F401RE1. EOCS As per the RM, if EOCS is "1" then EOC is set for each conversion,hence suppose...
Hello,What is the best way to multiplex an output pin to 12 output signals? I currently have 1 output sourcing 3.3v through a 1k resistor which works well, but need it multiplexed to 12 identical outputs. I see the STM32F373 has a max rating of 15m...
