I have successfully sampled my signal using SAADC example at a sampling frequency of 10 Hz. I am using a flag in the saadc_callback() function which I read from the main() function and accordingly instruct to write the sampled ... (more)
Hi, I am a beginner and trying to understand the SD card example for nrf52 DK. When I change the pins from the given configuration
#define SDC_CS_PIN ARDUINO_10_PIN
#define SDC_MOSI_PIN ARDUINO_11_PIN
#define SDC_SCK_PIN ARDUINO_13_PIN
#define SDC_MISO_PIN ARDUINO_12_PIN
to the following ... (more)
I'm using the PCA10056 with a SD card connected via P1.12-P1.15. When i use the FatFs example of SDK13.0.0, it's works fine. but when i use the FatFs example of SDK14.0.0, the ... (more)
I am using nrf51422, SDK 12.0.0, an SPI OLED display 128x32, and an SD card.
I want to interface an OLED display and an SD card onto the nrf51422. Although my SD card and the OLED ... (more)
I my application I am interfacing SD card with nrf52 using FATFS file system. I am observing some weird behavior while doing this. I have two SD cards, one of 2GB sandisk and another of 8 GB Transcend ... (more)
I downloaded the nrF5 SDK V12.2 from: https://www.nordicsemi.com/eng/Produc...
after unzip, I could see the SDCard library under "<Nordic Project>\nRF5_SDK_12.2.0_f012efa\components\libraries\sdcard"
I am a Keil user, so I ran ... (more)
I am working on interfacing SD card with nrf52. I am sampling SAADC at 1000 sps and trying to write over SD card as well as sending over BLE. Both operations are working fine but after
FR_DISK_ERR , entire code ... (more)
In my application of interfacing SD card with nrf52, I am using SAADC to sample the input signal at 1000 samples per seconds. These samples I am combining in 84 packets each consisting 12 samples and 20 bytes. In ... (more)
I am working interfacing SD card with nrf52 using fatfs example given in SDK 12.0.0. While writing to text file created in root directory, code gets stopped as size of file becomes greater than 300kB. Is it ... (more)
I have just started working on interfacing SD card with nrf52 using SDK 12.0. I have to write to SD card at a rate of 84 packets per second and each packet consists of 20 bytes. I ... (more)
I am trying to interface SD card with nrf52. For this I am using fatfs example of new 12.0 sdk. I can able to write the data to file but when I am taking the data from terminal ... (more)
I am interfacing micro SD card with nrf52 using fatfs example in sdk 12.0. As I am beginner, first I wanted to perform operations like read, write, delete and some basic functions with files. I am able to ... (more)
I'd like to use the NRF52832 (QFAAB0) / PCA 10040 / S132 development board as a data logger. For that I soldered a micro-sd card reader and started using the code found in another topic.
Any attempt to initialize ... (more)
Can nRF52 do MP3 decoding with SD card? Any example library we can use? thanks.
