it is a USB adapter. yes the card is small. i used both SDHC and SDSC protocols for supporting SDHC cards and SDSC cards.i think maybe the page you introduced doesn't have anything to do with what's going on here because my main problem is in the code. another thing which is noteworthy to...
hi I'm working on the code of a video door phone and I'm trying to improve it. with 16 GB SD card the pictures that the camera takes can be seen on the LCD but when I connect the SD card to pc using a SD card adaptor it shows nothing is in the drive. with 2 Gb SD cards it only shows the last...
I initialized the cs line and cs is controlled by the mikroc library I think. I don't have access to the functions of the mikroc library. about your last line, i think you made a typo because it is not clear what you mean. another thing that is noteworthy to mention is that the cs should be...
I connected SDI of PIC to SDO of the sd card (MISO) and SDO of PIC to SDI of the sd card (MOSI) and sck to sck ( pic18f452 has only one spi) also cs is connected to b4. the supply pin of the PIC and sd card are both connected to 3.3 volts the grounds are connected together.
I'm trying to write a text file to an SD card with a PIC18F452 using mikroC. I'm using a mikroC library named Mmc_FAT16 and I formatted the SD card to FAT, but I can't initialize the SD card.
I tried reading the error function and it returns 0xFF which means MMC/SD card was not detected
My...
Hi, i want to simulate a simple led blink register code with proteus but it gives me 9700 errors as shown below. The code works in real-time and in the Keil simulator. In addition, i tested proteus with another code that was produced by stm32cube and i just added my code and loaded the hex file...
pins 3 is not floating it is connected to a PCB pad as you can see in the PCB image I sent. the capacitor from pin 3 to the ground is for reducing sensitivity but the device's sensitivity is ok so I don't need it and I tried using it and it makes everything worse.
thanks for your responce
no, the inputs are not floating
do you mean just one resistor parallel with 10 uf capacitor or one resistor parallel with each 1uf capacitor near the ttp223 ICs?
Hi, I have designed a simple 4 pole touch key using ttp223 and modified it a couple of times. I encountered a problem using the final version of it. most of the time it works fine but sometimes when all the switches are on and I touch the third pole it doesn't respond to touching for 10 seconds...
no, I don't want you to look in the datasheets. I thought you asked a question and I answered you.
the sim800L datasheet says the voltage level is 3.3 volts. the ch340 datasheet says it works with 3.3 volts so why this doesn't work? the battery voltage is fine. maybe I'm missing something.
thanks for your reply. by changing the baud-rate I meant changing the baud-rate of the hyper terminal program that I used to interact with sim800L and I attached its photo. I think what you say is about connecting the sim800l to the microcontroller if I'm not mistaking. it is noteworthy to...
