Posted on August 02, 2016 at 02:31Hello, I am using the Segger J-Link+ to connect to my target board with the STM32F103RD chip installed. I connected all the necessary pins of the target board (TMS, TDO, TDI, NTRST, TCK, and RESET) to the correspond...
Posted on August 04, 2016 at 17:07Timer3 runs 2x faster than expectedI know what many readers are thinking but read onI set my STM32F746 (DISCOVERY PCB) for SysClk=216 MHzAHB Prescaler set to �1 thus HCLK = 216 MHzAPB1 prescaler set to �4 thus PCLK1...
Posted on November 19, 2013 at 23:19Where will I find app notes and development tools for the SPBT2632 Bluetooth module ? Is there a Forth language for it ? Or a monitor ? I want to do updates using the BT port. I cannot find any data for the AD...
Posted on August 04, 2016 at 12:49STM32F207VE Custom Board. I want to generate a PWM of 50-50 duty cycle with varying voltages (zero-to-maximum) like a DAC which gives output based on count. I do not have the schematic now. I'm directly viewing the ...
