ST-Link V2, STM32F103C6T6A "blue pill", trivial program (version of blink LED), after pushing code to CPU (using STM32CubeIDE 1.9.0 and a current-firmware official ST-LINK V2), the board(s) appear "bricked" and don't respond to ST-LINK V2.I am in nee...
I am using the STM32F103C8 (blue Pill) and have been having lots of troubles with reading multiple channels on ADC1. Here is my init code using firmware 1.7: ADC_ChannelConfTypeDef sConfig = {0}; /* USER CODE BEGIN ADC1_Init 1 */ /* USER COD...
Hi, I´m trying to communicate two blue pills between them using CAN bus, but when I try to run it, it doesn´t even finish the start up, because I tried to use a blink program selecting the CAN in the .ioc and not using it and doesn´t work.Does anyone...
I have an STM32F103C8T6 Blue Pill board, and I'm trying to get the RTC to function correctly when Vdd is removed. However, when I disconnect Vdd, the RTC doesn't operate as expected. Sometimes, when Vdd is supplied, the RTC starts counting from the t...
I bought Bluepill devboards from two different sellers, paying extra to hopefully receive genuine STM chips. When I use the Bluepill Diagnostics Tool written by Terry Porter, the tool reports passing on all counts except for one:Declared flash not 65...
Hi all,Total newbie here.I am seeing this error in Windows 11 Device Manager: "Device Descriptor Request Failed", when I plug the Bluepill to a PC using Bluepill's onboard micro-USB PortAlthough the Bluepill looks like it is running OK with the previ...
I am porting code from G473 to U575 because I need more flash and ram.Then I meet some issues on gpdma transmission size.For G473, I use dma to transfer data to timer ARR likes:uint16_t buf[65536] = { ..... };HAL_TIM_Base_Start_DMA(&htim1, (uint32_t ...
Hello community, I want to generate PWM with tim8 CH1 and CH1N (complementary) but i have an issue. CH1 pwm first pulse is 2x what it must be. My APB2 clock is 84MHz and i am generating an 500kHz PWM. How to initialize well the PWM with tim 8 to have...
i see somewere that the way to erase the flash is to do this instructions.FLASH_EraseInitTypeDef EraseInitStruct;EraseInitStruct.TypeErase = FLASH_TYPEERASE_SECTORS; EraseInitStruct.VoltageRange = FLASH_VOLTAGE_RANGE_3;EraseInitStruct.Banks = FLASH_B...
This is a repost of the message I left on the "STM32 MCUs Touch GFX and GUI" and I'm hoping that it gets some more traction in this section of the forum.Apologies for the repost. I'm in the process of migrating from an STM32F779AIY6TR to an STM32U5A9...
