StrAddr = random(0, flash. For systems that require high-speed memory in capacities of 1Gbit or higher, Winbond’s high-performance Serial NAND Flash is the new best choice for automotive OEMs, offering a combination. While (!Serial) // Wait for Serial monitor to open #if defined (ARDUINO_SAMD_ZERO) || (_AVR_ATmega32U4_) Only works with chips with more than one hardware SPI bus SPIFlash flash(SS1, &SPI1) //Use this constructor if using an SPI bus other than the default SPI. Required for Serial on Zero based boards #if defined(ARDUINO_SAMD_ZERO) & defined(SERIAL_PORT_USBVIRTUAL) I've included some example code below that does not cause this problem. So, your code is forcing the ♜ to try and establish SPI comms with the flash chip to write the second string while the first is still being written and, the third while the second is still being written and so forth. W25M02GWTCIG SLC NAND Flash Serial (SPI, Dual SPI, Quad SPI) 1.8V 2G-bit 1G x 2-bit 8ns 24-Pin TFBGA Tray. Your ♜ can cycle through commands faster than the SPI comms with the flash chip happen (in most cases SPI_CLK = System Clock/4). Winbond Electronics Memory Memory Chips Flash. After it is done writing - if successful - it returns a boolean 1 (True). The writeStr function takes some time to write a string to the flash memory chip. I took a logic analyser to it and found that the problem is not with the library. I've tested your code and it does not work - as you reported.
put your main code here, to run repeatedly: Serial.println(F("Initializing SPI Flash.")) But I'm getting unpredictable output.īelow I have attached the code : #include I'm writing string to 3 different address and trying to read string from that locations.
I'm facing issue while writing multiple data to various address. I'm using Winbond W25Q32 SPI Flash IC for data logging in my project.
