protofuse Posted August 3, 2010 Report Share Posted August 3, 2010 hello, I guess there is a little mistake on the documentation : http://www.ucapps.de/mbhp/mbhp_core_stm32_v2.pdf J8/9: the last resistor of the resistor array should be connected to J8/9:RC ... right?

philetaylor Posted August 3, 2010 Report Share Posted August 3, 2010 Hi. No J8/J9 only needs one pull-up resistor on RC as unlike J19 and J16, it only has a single RC line so the last resistor is unused. Cheers Phil Quote Link to comment Share on other sites More sharing options...

philetaylor Posted August 3, 2010 Report Share Posted August 3, 2010 Hi. This should make it a bit clearer, it is a front view like the one on thew CORE32 schematic. Cheers Phil Quote Link to comment Share on other sites More sharing options...
