Hello All,We have an custom board using stm32f446re controller which has 6 PIN SWD JTAG connector.We are using NUCLEO-F446RE kit as debugger to flash the custom board as explained in "6.2.4 Using ST-LINK/V2-1 to program and debug an external STM32 ap...
Resolved! We are using STM32F429VET in our design. Please tell me if the internal structure of I/O port of STM32F429VET is the same.
Currently, we are testing whether smoke and fire will occur when adjacent I/O ports are shorted. If the internal structure is the same, we think that a representative set of tests is sufficient. However, if the internal structure is different, then a...
Does the STM32F0's SPI TI standard is the same as "microwire SPI"?
Do anyone know if the STM32F0 SPI, programmed in the TI standard, not the MCU's ordinary SPI, is in fact the same of so called "Microwire SPI" as used into EEPROM: 93C66 (not regard to CS polarity)?Regards.
