sprintf not working when ADC started
I'm trying to send ADC results over to a receiver via UART, but somewhy the program freezes on sprintf() IF I have called HAL_ADC_Start_DMA() before. If I call sprintf() before HAL_ADC_Start_DMA() it works fine. However, I need to call it after start...
Resolved! SCKL frequency of SPI
Hello,I have set the BR bit in CR1 to 0 with the expectation of obtaining an 8MHz clock frequency. However, I am encountering an actual frequency of approximately 1.042MHz. Does anyone have an explanation for this issue, or should I consider implemen...
Resolved! STM32F042F6P7 (TSSPOP20 package): CAN availability on CubeMx
Using STM32CubeIDE (v1.14.0) with STM32F042F6P7 (TSSOP 20) to configure CAN pins on custom board. However the CAN peripheral is grayed-out when I open the IOC file in STM32CubeIDE. For pin assignments, PB8 is available for CAN rx but CAN tx is not sh...
hexdecimal number to send UART
Hi,I wanted to send hexadecimal numbers through UART. I am using STM32F405. Can it be done.If I am sending float number as 1.3456 string (text) to windows COM port to english language windows application field. If for example regional settings being...
Example script/program for I2C bootloader commands
Hi, I'm using a STM32G07x1 that will need to receive firmware updates from an embedded Linux CPU. The only connection between these devices is an I2C bus so I plan to use the ROM I2C bootloader to handle updates.I am aware of AN4221 that describes ho...
Resolved! STM32F413VGT6 DMA is triggered but no data is copied
Hello,I'm trying to use DMA with an Usart to receive incoming data in a circular buffer. Basically this is my code for configuration using UART5. I can send data, so i assume, that port und clock configuration is correct. When receiving data, NDTR is...
Guide for mapping a new chip as an external flash. Is external loader required ?
Hello I am in the task of adding a new flash as an external flash via QSPI interface with the MCU STM32F777ZITx.The flash that I want to add is S25FL256L as an external flash. I am not finding any references which I can use with this flash. Also it i...
RM0456: 10.5.4 unclear restrictions for STM32U59x/5Ax/5Fx/5Gx devices
RM 0456 10.5.4 Dynamic voltage scaling management writes under "System frequency steps on STM32U59x/5Ax/5Fx/5Gx device"===On STM32U59x/5Ax/5Fx/5Gx devices only, the maximum system frequency increase ordecrease in the VOS range 1 is 80 MHz.===This is ...
Resolved! STM32F407VGT6 Ethernet Module: Jambo frame feature?
Hi developers, I'm new to STM32 MCU, but recently need to use it for a automotive Ethernet board design. The ethernet PHY I am going to use supports the jumbo frame up to 16kByte. Do anyone happen to know if STM32F407VGT6 can also support this jumb...
