Posted on March 11, 2014 at 18:56Hi everyone, the title says it all. Scope tells me the timing is fine and the signal looks like it should. Receiving on the other end works. Except the MSB always being set to 1, no matter if I try to send values hig...
Posted on March 12, 2014 at 12:04Hello everybody! Yesterday I upgrade my stm32f4 discovery st-link v2 firmware. After that the coocox give error at erase flash. I have another board with old firmware, this is working well. What can I do this sutiati...
Posted on March 03, 2014 at 17:40Hello everybody. I am developing some test firmwares on a STM32F103 based board. After some working programs using the sleep mode, now I need to do some experience with the much more powerful standby mode. I need to ...
Posted on February 06, 2014 at 11:54I am using IAR with STM32-Value line discovery board. I am trying to program the kit but not getting programmed giving error like below, Fatal error: ST-Link DLL not found Session aborted! Can any one guide me ...
Posted on March 11, 2014 at 19:18Hello,I am using the STM32F303 with SPI1 in slave mode and no data packing. I am seeing an issue where I will get an interrupt when a byte is received, but the status register says that there is nothing in the recei...
Posted on March 11, 2014 at 21:48I'd like to model if it's practical to drive an STM32 output into a transistor. I've got some Optimos 3 transistors with a 2.8v Vth:http://www.mouser.com/ds/2/196/BSC340N08NS3G_rev2.6-76670.pdfThe transistor would b...
Posted on March 11, 2014 at 02:34LD8 LED is ON (USB over-current) regardless to program. Furthermore receiving data by UART3 using pin PC11 is impossible, but with PD9 works fine. Earlier I had no problems, and now after connected the board to the c...
Posted on March 11, 2014 at 16:50Hello everybody,I'am trying to use analog watchdog on STM32F051K4 and I face some problems. I want to measure a pulse on PA0 (ADC_IN0) of 100us wide with an 1V amplitude above 0.5V offset. There is no example on this...
Posted on March 11, 2014 at 08:52HelloI am trying to configure a timer to get interruption at 12 MHz on the STM32F429 Discovery Kit.I am currently using TIM2 and I cannot reach more than 2.25 MHzTheoritically I could reach 45MHz right?Thank you for ...
Posted on March 11, 2014 at 02:30I plan to make a inverter by using STM32 CPU. STEVAL-ISV003V1 is a good example. But I need to get its firmware.How can I get it? or I can only get it by buying this board?
