Posted on January 16, 2013 at 23:13I'm developing an application on a STM32L Discovery card (with an STM32L152 MCU), although our final target is an STM32L151. I wanted to try out the system memory boot mode, that is boot0=1, boot1=0, and then usin...
Posted on November 12, 2012 at 14:47The STM32L1xx datasheet says that the temp sensor sample time will be between 5 and 10 uSec. The manual confirms this, saying that you should use a 10 uSec sample time. With the ADC clock running at 16MHz, this ...
Posted on October 19, 2012 at 18:51The STM32L1xx reference manual has this text in the DMA section: The 7 requests from the peripherals (TIMx[2,3,4,6,7], ADC1, SPI[1,2], I2Cx[1,2], USARTx[1,2,3]) and DAC Channelx[1,2] are simply logically ORed...
Posted on October 19, 2012 at 17:49I'm trying to use the ADC on an STM32L1xx to read a single channel with a sample rate based on TIM2. I plan to use a double-buffering scheme, so I want to set it up to DMA into a buffer with half-complete and full...
Posted on March 28, 2013 at 21:50Hopefully I can give back a tiny amount...this forum has been SO useful to me. To use the 8MHz signal coming out of the ST-Link chip on an STM32L Discovery board, you need to short solder bridge SB17 on the Discover...
Posted on February 06, 2013 at 20:11Ok, solved (after going away for a while and coming back). It works great! I mis-read the Discovery card schematic. Boot1 (PB2) is pulled high by default, not low. You have to either jumper it low or close a s...
Posted on January 18, 2013 at 00:39Oh! It is supposed to respond to the 7f? Hmm. Unless I was messing up using RealTerm, it did not. Have to play more. Thank you!
Posted on January 17, 2013 at 03:12Hi Clive,You are right. PA9 and 10 connect to LCD common 1 and 2. I generally have been removing the LCD since it won't be on the final product, but I did not on this one. I just removed it and that made no diff...
