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...
Hello everybody! I have a sine-wave array, that I throw to the DAC, triggering it by TIM6. When the TIM6 interrupt routine is responsible for supplying samples - everything works fine, but when I try to use DMA nothing works. The DMA keeps spitting t...
Hi, I want to make communication between stm32h563zit6(Nucleo-H563zi) via USB communication, i have tried configuring various UART/USARTS but not able not make communication.I had verified it by sending some data from stm32 ,and tried to see it on ...
我用板子A：STM32H743VIT6，HAL库开发，版本v1.9.0HSE=20M，主频480M串口1使能，DMA发送，IDLE+DMA接收数据。发送使用1ms定时器进行DMA串口发送，发送间隔1ms，发送数据长度18字节。板子B：STM32F405RGT6，HAL库开发，版本v1.27.0HSE=8M，主频168M串口2使能，DMA发送，IDLE+DMA接收数据。数据发送使用1ms定时器，10ms间隔通过DMA发送数据，发送数据长度18字节。连线板子A的Tx-板子B的Rx。板子A的Rx-板子...
Hello,I am new to dual core controllers and I had a question on how the internal ST bootloader works for STM32H755, till now I have used STM32F4 and STM32F7 series with single core and i have loaded User code using UART and ST Flash Loader, as I unde...
