Hi, I haven't check the forum lately and I did not see your post before. Here is my program it works great!

I did test the new KS0108 Glcd component, it works excellent! I did test the Glcd with both orientation parameters, 0 and 2. I connect CS1 pin to CSA and CS2 to CSB. I'm want to appreciate your support towards this Glcd implementation, it's good to have more options to work with. According with the ...

Hello Benj, that's great news! thanks a lot for your help. The display has a high visibility, good processing speed and a very good display area. It's a good component. I will check your Display component as soon as possible. I will let you know how is it working. Thanks a lot again!

Hi, I was trying to get the KS0108 196x64 locally but I surprisingly found that it's not available, so the only source available was from China. I found a source on Ebay and I ordered one, I never though I was getting a 196x64 display with only two chips! :shock: So far, The only options on flowcode...

Hi Benj, I did download the latest Flowcode 6 update, This fixes are already loaded into the latest update? If not, would you please post the necessary steps to perform this operation? I have never done it before and I don't want to do it wrong and mess something up.

Hello Benj, thanks a lot for your quick response. I did open the file after being created and it did but not in the .txt format so I was not able to see the contents using my SD card reader. I was expecting to see the contents after the file was created and contents where copied to FAT. I did not tr...

Hi guys, i forgot to say that the " create file macro " does not work correctly. I tried and I was not able to read the contents even when I tried to opened it using world pad. However, it works perfectly when I create the file using world pad. So, open world pad on windows accessories and...

It works!! I tried changing just the initial pre-scale to 128 as discussed but when I tried it did not work. This time I was having communications with the SD card and it was sending back a byte "0xED - Sector Bytes Error". Then after posting the previous message I decide to try a differen...

HI, Benj. Thanks for your quick reply on the FAT issue. I was very excited when I red your post that I want it to try it immediately, unfortunately it did not work for me. Now it just return the byte 237 "0xED - Sector Bytes Error" on all my cards. I retrieve the return code from the forum...

Hi Benj, I tried one of the WIKI examples (FAT_Read_File) with my hardware but it does not work, looks like there is no communication with the SD card. The return value is 0xFF but it retrieves this value even with MISO and MOSI lines disconnected. An example from the Arduino website is able to comm...

Hi Kersing, you were right, the SendChar command in RS-232 communications is easy and it works perfectly but the Send_String command did not work for me, it just send the first three letters. Do you have and idea of why? I will appreciate your feedback. Thanks a lot.

Great! Thanks a lot.

Hello dear Kersing, with all the respect you deserve, the purpose of this thread was to find out if the FAT component worked or not. The idea was to post and hope for someone who could share this information with me (if it works or not based in project experience with Arduino) because I had doubts o...

I made a program model to copy contents from EEprom to FAT and vice versa using the Arduino Mega. The program only works on the simulator and not with hardware. I already tested all my hardware, my control voltages are at 3.3v (MISO, MOSI and CLK) and CS is 2.8v. I'm using a SanDisk SDHC class 4 wit...

Thanks a lot for your feedback, I hope to get help soon to solve this issue.

would you take a look to my program? Can you tell me if its right? I will appreciate that.
I will check with another card. But why the arduino program actually did communicate with card and flowcode didn't?

Hi guys, I did a program model using the Arduino Mega for saving EEprom contents to FAT and downloading back to EEprom, in the simulator the program works. I start by writing four lines of data to EEprom and then I upload to Fat three times (three different sectors). Then, I opened the file EEprom.t...

I believe I got the right idea.

Thanks a lot for the information I could not find it anywhere when I google it. Now I got A better understanding of what has to be done (I believe at least). Unfortunately, I couldn't make the examples from WIKI website, except The FAT_Read_File which I could make it work perfectly (I learn a lot fr...

Hi guys I finally succeed with my program! I'm able to create a file and load wherever I written at EEprom memory to a FAT memory. Now, The 512 bit file created is just for the simulator??? Or all the files created on SD card will be at 512 bit in size when using my hardware??? Do I have to create f...

Hi thanks a lot for the valuable information. I got another question regarding interrupts; When I set the pins to enable the interrupt in the bottom left corner of the chip lay out there is three different color boxes: trigger on rising edge (red), trigger on falling edge (gray) and triggered on bot...

Thanks a lot for your reply, I was checking the initial value property but I did not see how can I set it. Since the controller has the ability of store this values by hand what will be the easiest way to upload this eeprom bytes to an SD card? What function from the FAT menu will be the best? I did...

Thanks a lot for your help. I will try it today.

Hello guys, I finally finished my Arduino Mega project of an automated oven controller. My controller stores over a hundred recipes containing information such as recipe name, baking time and temperature and other functions, the only thing you have to do is to select the recipe and hit start. It per...

Thanks a lot for your reply Benj. How do I set this up? You said to use the interrupt macro but do I have to choose custom "interrupt on" and place the code there? because in order for the interrupt to work when this pins are used this is the way needed, right? Or are you talking about pla...
