Posted on November 21, 2013 at 15:51Hi, I am having a problem with using the I2C on the STM 32 F4 discovery to read 3 DevanTech SRF-08 ultrasonic sensors, There was a previous post on this matter, but it was unresolved as far as I know, clive1 did i...
Posted on February 26, 2013 at 07:38Hello, I try to make I2C on PF6/7 on the STM32F051C6 (48 Pin device) working. To get what AF to use, Ref man points to the datasheet. But the datasheet is not clear to me, it has a AF Table for PortA and PortB an...
Posted on November 21, 2013 at 17:52Hi,I am using SPI2 with DMA1 on STM32F427 to communicate with an external processor. The problem is that when the data on MISO and MOSI pins (PB14 and PB15) are somehow corrupted i.e. the data comes out as shifted...
Posted on October 23, 2013 at 21:20Using the 3 channels of the SDADC in Single Ended Zero Reference Mode, Gain 1, with a SDREF at 2.5V. Spec lists gain error of -2.4% to -3.1%, but our devices appear to have a positive gain error of approx +2.8%. ...
Posted on November 22, 2013 at 00:44Hi there, I've got a problem here using NVIC_SetVectorTable(). I have attached my test programm, which is held very simple and does: - Init Leds&UserButton - make sure the ''new'' Vectortable is 0x200-aligned - Co...
Posted on November 21, 2013 at 16:23Hello, I have a problem with the RCC_ADCCLKConfig, I want to change the ADC frequency and I followed the example from st. /* Configure the ADC clock */ RCC_ADCCLKConfig(RCC_ADC12PLLCLK_Div64); /* Enable...
Posted on November 22, 2013 at 11:57 The stm32 chip has a error for I2S in slave mode (stm32f40x Errata sheet 2.4.1). 2.4.1 In I2S slave mode, WS level must be set by the external master when enabling the I2S Description In slave mode, th...
Posted on November 21, 2013 at 22:08Hello Everyone,I'm new to the IAR Embedded Workbench IDE (IAR embedded workbench for arm V 6.70.1.5794, common components version 6.6.5.2892). I have the STM32L152C discovery board and a ''Hello World'' sample p...

Posted on November 21, 2013 at 15:25Hi, I would like to ask if there is a way to clear the FRLVL and RXNE bits in SPIx->SR in order to ignore everything that has been received before. I have some routines that only send data and other that will als...
