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...
Hi Team,We used the STM32H753VIH6 in our current design and validatedWe are looking for the leakage current data of the STM32H753VIH6.We want to validate the leakage consumption under no load condition.Please provide the data on this. Regards,Sathya...
Hello Dear Community,I want to capture and decode a bitstream on STM32F746. The bit rate is 60ns/bit. Data is encoded using 4b5b and has a unique code for start of frame and no end of frame.What I have tried so far, is to configure TIM2 (APB1 timer c...
Hi ST community,I am looking for some help with selecting the lowest QFP pin count STM32 for my project.The STM32 will connect to the following below:18/24bit RGB LCDFMCQSPImaybe MIPI (Optional)Any FMC part number suggestion?Thanks
Hello,I’m working with the STM32F407VG microcontroller and I want to establish communication between the PC and the board using CAN protocol. Which USB-to-CAN adapter is recommended for CAN communication with Board.[STM32 Board] --- [USB-to-CAN Adapt...
