Posted on October 08, 2014 at 14:48Hello :),I need help to solve the communication between processor C805 and BL module. Devices communicate via UART (serial port -> TX / RX pins) and I need to do a basic setup. Then send it AT commnads BL module. ...
Posted on October 04, 2014 at 01:46I want to have an interrupt that is triggerable by software, but without also having it be hardware triggerable. This is easy if there is a spare pin on the microcontroller to dedicated to being a useless pin. But ...
Posted on October 08, 2014 at 02:07Hi All, I have configured the ADC according to the initialization code below and then try to to a conversion to read the VREFINT voltage so as to calculated AVDD. The initialization appears to work ok and the conv...
