Hi again.
I made an experience.
First I put two variables from your code:
double height = 5.84; uint32_t age = 45; fram.put(30, height); fram.put(40, age);
Then I read right values 5.84 and 45.
When I added the third instruction put:
double height = 5.84; uint32_t age = 45; uint8_t val1 = 100; fram.put(30, height); fram.put(40, age); fram.put(50, val1);
after reading it with get I obtained: 5.84 100 100
Hi Bizan Nishimura .
I have trobles with your FRAM library.
I use MB85RS64V 8kB SPI FRAM wired to ESP32.
At the beginning all seemed to be fine but next heapend something strange. When I write few variables one after one I recived only last written value.
For example my code:
include
include
FRAM fram(8);
define SCK 5
define MISO 2
define MOSI 0
define CS 15
SPIClass spi = SPIClass(VSPI);
void setup() { Serial.begin(115200);
spi.begin(SCK, MISO, MOSI, CS); fram.begin(15, spi, 4000000); fram.put(30, 200); fram.put(40, 123); }
void loop() { byte a = 0; byte b = 0;
fram.get(30, a); fram.get(40, b);
Serial.println(a); Serial.println("-------"); Serial.println(b); Serial.println("========="); delay(1000);
}
When I run this code I recive only this:
123 // instead 200
123
Am I doing something wrong or my memory is damaged or maybe something else.
Even yor example FRAM_test1.ino code return something like this:
name: - //here is wrong height: 5.84 age: 45 Done!
I will grateful for your answer
