Posted on December 02, 2014 at 03:49HI Group, I have a development board which is acting as SPI Master connected to an STM32 chip on another prototype board acting as SPI slave. I cannot change anything on the development board. I am facing an i...
Posted on December 04, 2014 at 06:47 Hi, Actually, I dont have the schematics of the Gemalto Board, so I dont know for sure what is there between the SPI pins on the chip and the ones on the header. I only have the option to explore what is hap...
Posted on December 03, 2014 at 03:34Hi All, I reduced the wire length of the clock from 6inches to 3 inches. Same result. Would it help to connect a schmit trigger chip so clean up the MOSI Line? Vineet.
Posted on December 03, 2014 at 03:18 The probing is done at the STM32 side which is the SPI slave. I will check on the slew rate. Regarding the shortening of length do you mean the clock or MOSI pin? The NSS in STM32 can be software co...
Posted on December 02, 2014 at 12:22 Hi JW, How do you know that? What is SecureCore 300? [Vineet]: Because I am able to get correct data for 100, 250 and 500kbps. I cannot disclose too much about the chip, but it is cortex M3, be assured...
Posted on December 02, 2014 at 10:10Actually, the SPI slave at the driver level is running faster than the master. So I dont think that may be an issue. Also, I am taking the 5V and Gnd power from the Gemalto board which is connected to PC over USB...
