I have got 3 identical boards with STM32u5a5. For improving ADC accuracy I want to calibrate Vref using Vrefint. This is working fine on one board, but on the other two boards Vrefint reads as 0 using the same software. Other ADC channels seem to wor...
Posted on September 19, 2015 at 00:10 Hi to All, I make a step ahead with adding for testing purposes in usbh_cdc.c alternative staff in case of CP2102: static USBH_StatusTypeDef USBH_CDC_InterfaceInit (USBH_HandleTypeDef *pho...
Hello, I am trying to use FDCAN but for some reason interrupt is not triggering. Im using PEAK CAN to send and recieve messages. With osciloscope I can see the data being transfared to the STM board but the interrupt doesn't trigger. The speed I wa...
i am trying to use multiple channel on a single ADC to measure certain voltages. what i have noticed is that let say i have selected 3 channels now in configuration of cube MX i select no of conversion to 3 and as soon as i do that Ranks get added be...
Greetings,I have STM32Cube IDE installed, created some test apps, blinking LED's, RTOS threads, mutex and so on,writing on UART2 (virtual serial) is working well as I have working output on virtual COM port using putty on serial.I want to access UART...
I am aware of the special bits to stop the IWDG and WWDG while the core is halted, but is there a way (option byte, SWD command, SFR, etc.) to configure an STM32G4 so that it will ignore the nRST pin being pulled low? I am particularly interested in ...
Hi, I have ported the Open Bootloader to the STM32G431 and has flashed it and is able to communicate with it over FD-CAN. Is there any program out there that I can use to flash programs using the bootloader over FD-CAN? maybe the CLI version of the S...
Hello, I have been prubbing to run SPI transmission using DMA for some time now. So far I am trying to send a variable, but something is not working. Without DMA it works without any problem. Would anyone be able to help?
Hi,I'm running two timers on STM32F303 which do square wave output on two hardware pins. They are clocked by the 72MHz internal clock. They count down to 0 and reload from ARR register, which sets the output frequency. The two timers run perfectly sy...
Posted on January 30, 2016 at 17:47Hey folks, I've been working on USB host driver for MIDI, and so far I can enumerate the device and get data flowing. But as soon as the device is attached I get crazy numbers of interrupts related to IN transactio...
