Posted on December 07, 2015 at 04:02For the Chip STM32L151RBH6, we have only 1 bank, EEPROM writting halt the MCU. I make a test program to repeatedly write EEPROM. Use the code like below to write EEPROM:
*(__IO uint32_t *)addr = data;
100 times repeated write consumed 673ms: 6.72ms once.
50 times repeated write consumed 336ms:6.72ms once
The Reference Manual addressed: ''This function can be executed from any memory. If it is from the same bank the program is stalled for one Tprog.'' So I tried to implemente the write from Ram function. The result didn't change great.
1. 50 times consumed 324ms, 6.47ms
2. 100 times 663ms, 6.63ms
