Posted on March 12, 2016 at 01:11So I got myself a STM32F4 discovery board and the STM32F4 Expansion board to play with Ethernet, spend a descent £40-£50 on ST's products just to be told that the example projects exceed the allowed 32KB code size by...
Posted on December 16, 2015 at 15:40Hi. I'm trying to calculate CRC on STM32F303 using CRC peripheral. I check the correctness of calculation with this on-line application: https://ghsi.de/CRC/ But I have problems, when I want to calculate CRC abov...
Posted on March 02, 2016 at 09:19Hi,I know there's not such easy think than helping someone describing its issue with prose, but here I try.In a current STM32F091RC building, linking and running project (gcc makefile), I wish I could basically cut-a...
Posted on March 14, 2016 at 15:48Hello there, I´m testing STM32F7 Discovery board, is somewhere demonstration example for Eclipse (openstm) or only for IAR?
Posted on March 10, 2016 at 09:28Greetings,This will probably be an amateur question for most of you but I need to make sure.I have a project in which I use an stm32F407VGT6 mcu and I need to make another board.I don't have access to those mcus any...
Posted on March 14, 2016 at 16:47 Hi guys, I have maybe not a problem, but small issue with ST32F466RE nucleo board. I do some one way communication with a slave device (only writes). Everything works fine until pin reset. Power ...
Posted on March 14, 2016 at 16:08Hi, It's about CS43L22 (Low Power, Stereo DAC w/Headphone & Speaker Amps) available on STM32F4 disco-board.So according to this schematic:
Posted on March 14, 2016 at 16:07Hi. Ref. manual says that PWM output is '0' when CCR register is 0. I noticed a difference when I look output signal on a scope while CCR was set to 0. I have ARR set to 16383, timer frequency is 72 MHz. Thus, the pe...
Posted on March 14, 2016 at 14:57Hello,I am working with ST-LINK/V2 and would like to use 2 probes simulteanously.The 2 probes are recognized with ST-LINK but I can't connect them simultaneously.I have tried to lauch 2 ST-LINk or to connect them wit...
Posted on March 10, 2016 at 21:04Hello,I'm experiencing an issue with a STM32F101 using an 32.768kHz LSE.The LSE being used is the 7pf variant shown in the link below with 9pf caps as CL1 & CL2http://www.ecsxtal.com/store/pdf/ecx-71.pdfThe problem i...
