Detailed Description
Driver for the nRF51 NVMC peripheral.
This driver allows writing to the non-volatile memory (NVM) regions of the nRF51. In order to write to NVM the controller must be powered on and the relevant page must be erased.
Function Documentation
| void nrf_nvmc_page_erase | ( | uint32_t | address ) |
Erase a page in flash.
This is required before writing to any address in the page.
- Parameters:
-
address Start address of the page.
Definition at line 43 of file nrf_nvmc.c.
| void nrf_nvmc_write_byte | ( | uint32_t | address, |
| uint8_t | value | ||
| ) |
Write a single byte to flash.
The function reads the word containing the byte, and then rewrites the entire word.
- Parameters:
-
address Address to write to. value Value to write.
Definition at line 64 of file nrf_nvmc.c.
| void nrf_nvmc_write_bytes | ( | uint32_t | address, |
| const uint8_t * | src, | ||
| uint32_t | num_bytes | ||
| ) |
Write consecutive bytes to flash.
- Parameters:
-
address Address to write to. src Pointer to data to copy from. num_bytes Number of bytes in src to write.
Definition at line 104 of file nrf_nvmc.c.
| void nrf_nvmc_write_word | ( | uint32_t | address, |
| uint32_t | value | ||
| ) |
Write a 32-bit word to flash.
- Parameters:
-
address Address to write to. value Value to write.
Definition at line 87 of file nrf_nvmc.c.
| void nrf_nvmc_write_words | ( | uint32_t | address, |
| const uint32_t * | src, | ||
| uint32_t | num_words | ||
| ) |
Write consecutive words to flash.
- Parameters:
-
address Address to write to. src Pointer to data to copy from. num_words Number of bytes in src to write.
Definition at line 113 of file nrf_nvmc.c.
