Posted on March 22, 2016 at 10:12 I have recently reversed-engineer some HAL source code and I see that sometimes a temporary variable is used to manipulate a register, for example uint32_t tmp = 0; tmp = hdma->Instance->CR; tmp |= hd...
Posted on March 21, 2016 at 10:56sdram clock run in 90MHz;LCD clock run in 24MHz.it not work(display ng).but LCD clock run in 18MHz,it work(display ok),but it looks blink,because reflesh rate low.huw to solve it?
Posted on March 17, 2016 at 23:09In the newer STM32 models, the I2C module allows to respond to multiple addresses in slave mode, through using a mask for own-address in the I2Cx_OAR2 register. However, if this is used, reserved addresses 0000xxx an...
