Posted on August 25, 2015 at 16:53I know it's a recurring problem. I could'nt make I2C2 work on my STM32F401VET.When I use RCC_APB1PeriphClockCmd(RCC_APB1Periph_I2C2, ENABLE);I2C2->SR2 =2No matter what I do.I try many work around proposed on this fo...
Posted on August 28, 2015 at 10:58I am trying to run an existing code developed in Eclipse + GCC in IAR workbench. After making all the related changes, the code compiles successfully. Now when I try to run the program, at the point where there is a...
Posted on August 27, 2015 at 13:08Hi,I've been looking over an example of master/slave I2C communication using an interrupt and I just can't seem to figure out how it actually works. The description is really vague and the HAL documentation isn't mu...
Posted on August 26, 2015 at 17:32 I am quite new to STM32 and try to do my second application using an STM32L051K8T6 where I need a PWM signal that is aborted when current rises above a treshold. It didn't take me too long to get this working o...
Posted on August 27, 2015 at 16:07 EDIT: Problem solved. When calling GPIO_PinAFConfig in lines 19 and 20 below, I used GPIO_Pin_# rather than the correct GPIO_PinSource#. All my other uses of AF peripherals was correct- I just messed this one u...
Posted on August 28, 2015 at 09:05Sorry for my bad English, I use a translatorMCU: STM32F429I use CoCoox. I wrote code to initialize the camera. Interrupts DMA2_Stream1_IRQHandler and DCMI_IRQHandler triggered, but the buffer is empty when I want to...
Posted on August 21, 2015 at 17:49Hi. I am working on the temperature controller using stm32l052. I use inbuilt temperature sensor. What am I doing wrong? TEMP130_CAL_ADDR value here is 0x0395 = 917dec TEMP30_CAL_ADDR value here is 0x029d = 669dec T...
Posted on August 27, 2015 at 02:02Hi, I am running a small program on my nucleo board and it would be very helpful to read back the RAM contents during processing. The IRAM is set in Keil to start @ 0x20000000. But if I set a breakpoint in my code a...
Posted on August 27, 2015 at 22:51I have a STM32F7746G-DISCO board and am trying to get the STemWinYT graphing working. All is good until the graph data fills up. i.e. i call GRAPH_DATA_YT_AddValue() 1 more time than the MaxNumItems given the the G...
Posted on August 27, 2015 at 16:47Hi We are using STM32F302C, schematic is attached. some boards when powered on take more than one minute in order to get the application running, this problem happens only in stand alone mode ''without connecting IC...
