FLASH data is not held
hey thereI have a STM32f030k6t6 which I wish to store data in its FLASH eeprom.the thing is sometimes data on certain addresses are cleared in startup! here is my codeHAL_FLASH_Unlock(); EE_Init();//eeprom initiallization EE_ReadVariable(ID_FLASH_ADD...
Hello everyone. I have three questions. flash memory write function.
1. Receive binary file from MCu1 to UART and save it to SD card (or EEPROM).2. Write the binary file stored in the SD card (or EEPROM) to the specific flash memory area of MCU2.3. Write the binary file stored in SD card (or EEPROM) to the specific ...
Unable to transmit more than 4 bytes using I2C DMA LL examples
Hello,I am currently using STM32L0538 for my project. I have refereed I2C DMA LL examples from STM32Cube_FW_L0_V1.12.1 and ported the same for STM32L0538 discovery board. I also got it working, i am able to transmit and receive data using i2c DMA. Bu...
STM32F051R8 (64-pin on MB1034B) and RM0091 - can't find alternate function (AF) specifications for PF6/PF7 to enable I2C2.
I'm setting out to configure I2C2 on STM32F051R8. RM0091 (dm00031936) table 13 (pin definitions) has two rows describing pin 47/48 (LQFP64 package) PF6 and PF7 as being configurable for I2C2_SCL and I2C2_SDA.I'm now looking for alternate function (AF...
Resolved! STM32L476RG VREF 2.5V to AD?
VREFBUF_TypeDef adRef; adRef.CSR |= VREFBUF_CSR_ENVR | VREFBUF_CSR_VRS; adRef.CSR &= ~VREFBUF_CSR_HIZ;Can someone tell me why I cannot set the AD VREF+ to 2.5V?
Resolved! Trigger ADC1 conversion using TIM3 using registers
Hello,I am trying to have analog voltage converted every 2 seconds using the TRGO signal from TIM3. Without much success. For now, I managed to generate interrupt of TIM3 and in TIM3 Handler to use software trigger for ADC. Here is the code:TIM3:void...
[SOLVED] Issue with custom External Loader for IS25LP256D on STM32F746 - update to V2.5.0 & deinit qspi in Init()
I've made a custom external loader for IS25LP256D on STM32F746. It works well in general except for one problem. Verify doesn't stop when "Verify Programming" is checked. Memory-mapped mode works well, which means reading is good. Erase() and Write()...
Resolved! Sample project using STM32H743 and ISSI IS25LP256D (QSPI chip)
Hi Folks,I'm working with a custom board using STM32H743 and wanting to work with a ISSI IS256P256D QSPI chip.I tried using STMCubeMX to create a sample project. when I start the project using the "Start my project from MCU" it creates files but th...
External loader for external SDRAM
HelloI want to download my code in the external SDRAM connected to a STM32H743 for debugging purpose. I use the STM32CubeIDE, I wrote an external loader .stldr to configure the FMC.In the debugger tab, I selected the external Loader but it fails to l...
