Forum Post: RE: Need help in Hardware issues
Well the datasheet of the processor specifies the values. Don't know about type but a 1K resistor for 5V would need a maximum rating of 25mW so pretty much anything. For other Pins it will depend on...

You can now specify the pin configuration you require when you go into the low power mode, in the pin configuration that will be used in the power profile, for the sleep pin cfg table. For example,...

Did anybody work with QSPI of SK-S7G2 ? I need to write a single byte to external qspi flash on s7g2, and read it. Working example projects please?

Hello Jeff, Mass Storage device shouldn't use FileX, as the host system controls drive formatting. You just need to provide it with read/write access. I have an improved version of the Mass Storage...

Hi Karol, My question is regarding a USB MSD Host, not USB Device.

Sure. Quick question though do I need 1 file or two? Again, the OOB demos use two files loaded at different addresses.

Karol, Can you define 'improved version'? We've implemented and tested the USB Host (S7DK board) and get a dismal ~1MB/sec throughput result. That's far less than I'd expect (theo. is 60MB/s). Does...

I just tried with the RSK board and it works. The RSK board has a single 32MByte SDRAM chip, but I made it think it has two 8Mbyte chips (with a 8Mbyte blank hole in the middle) memory {...

I want to have a small video capture window with graphics around it. I've experimented with alpha blending, but I'm not seeing quite what I want. Is there a trick to creating "transparent" pixels on...

Sure, you can make the toggle conditional on the state of the button. I'm not sure if that helps, but this should be a simple C coding exercise.

Has anyone ordered from this website? http://newtc.co.kr/en/ They have an interesting "dongle" device for programming chips with Windows or Linux machines.

Hi there, Can you give us more information about the tools you are using? Which development board, and what graphics tools are you using? RZ can handle multiple layers with transparency, which is...

Sure. We're using a custom board of our own design (using a RZ/A1M chip). We're driving a 1024x768 LVDS display (from NLT, not sure of the exact model number). My code is based on the CMSIS-RTOS...

Do you mean according to sinking current the resistance should be needed. Using V=IR?
View ArticleForum Post: RE: Need help in Hardware issues
Thats just how I calculated the power through the 1K at 5V. The 1K is specified in the datasheet, the power is only 25mW if there is a constant 5V accross it so any resistor of 1K should do. Each pin...
