hello guys, I want to config SPI to communicate with TJA1145 .the 4 pins are shown in the picture. but I test the signal by OScilloscope and I found nothing in the four pin which means no meaningful signal. for example the CS pin is always high and n...
my dear guys, I want to take use of STM_2 as a system tick for OS schedule, but when the condition for STM_2 compare interrupt satisfied , the PC can not jump into ISR ,the PC jump into a illegal position.thanks pretty much for your suggestions.
my dear guys, I download a hex into MCU by UDE tool, but after doing some reset action ,it can never be connected anymore, could be pls help me to review the memlay of this hex file and does it destory some key area or contents of the flash ?
there were several error handlers in the software and I write here for other people's reference .I didn't cojfig IVPR register correctly, IVPR should be set as the start address of interrupt table. but IVPR was 0 at first ,so core2 jumped into 0x000...
by the way ,is there any relationship between clock setting and the ISR here? because I didn't do any clock setting before I began the STM_2 function coding.
thank you pretty much ,the SBC is enable in the plant state even if I do not plug in KL15(I only plug in KL30) ,but after I download SW and re_initial SBC, the SBC will not power on MCU if I don't plug in KL15. so this is a fool mistake made by me.
