● Significance of the Watchdog 1、 The c language execution process In microcontrollers, c programs execute sequentially starting from address 0, where the PC pointer indicates the current execution address. For the STM32F407, as the code executes, the PC pointer continuously moves along the memory addresses. When it reaches the last statement of the main … Read more
Previously, when using STM32’s SPI to control many external chips, there was only one chip select for a single SPI peripheral. How can we achieve independent chip selection for one master and multiple slaves? SPI Bus Topology Generally, the SPI bus is connected as shown in the figure below, with one master and multiple slaves. … Read more
1. Introduction The previously made test circuit board for the STM32F373 did not have the 16-bit high-precision ADC pins exposed, so a new board was made to test the performance of the 16-bit ADC in the F373. 2. Designing the Circuit Board Based on the previous experimental circuit board, the original output pin header was … Read more
