Taking IPB017N10N5 as an example, there are few parameters about the diode in parallel and there are no descriptions about the diode reverse recovery current limit, diode shutdown device maximum power limit and SOA, where can I get this part of information? Where can I get this part of information?

你好，我想问一下，串口如果使用DMA模式的话，有什么方法可以让我获得串口接收到的数据，除了函数getbuffer以及DMA通道回调事件触发的时候能够获得其handle的buffer。这两种方法虽然可以得到串口收到的数据，但是如果之前配置的缓存区没有满的话，我们是拿不到buffer，因此也拿不到他的数据。
此外，我也用了CyU3PDmaChannelSetWrapUp函数，能够在DMA通道缓存区未满时将其强制提交，从而获得缓存区。这个方法虽然好，但是我用一个线程任务专门执行这个函数，它竟然有次数限制，当超过了某一个次数的时候，它就不再使用，这是怎么回事呢？

Hello everyone, my board needs to use a SmartPIM1 series IGBT module: FP35R12U1T4, according to the SmartPIM1 assembly instructions AN2009_09, PCB boards have a layer of tin after the metalization of the aperture, I would like to ask this layer of tin is plated with the surface treatment using the sinking tin process? It seems that most PCB manufacturers nowadays are spraying tin, and there seems to be only copper on the inside of the holes, will this affect the assembly?

Another problem is that according to the assembly instructions the board needs to be drilled between 1.12mm ~ 1.15mm, I can find the best precision factory crimp hole hole diameter tolerance is also ± 0.05mm, it seems not quite able to meet the error requirements. I would like to ask you to play this kind of board to find what manufacturers to meet the requirements?

Hi infineon

As the title said, I got a problem with "Vddk", I use the next formula to configure "Vddk", but some products(not all, same program) will exceed the threshold(±2%) when ambient temperature increasing, and the calculated value close to low boundary? Could you give me some advise? Thanks

Hello,

we ported the wifi stack in our new product, it has a WiFi stability issue, mainly it shows SDIO bus communication error, we made a restart stack when it happened but we don't know where is the root cause, can you help us with this?

Thank you very much!

I am trying to use the BLCD Shield. I am unable to update setparameter(), which led me down the rabbit hole of downloading Kiel uvision5, buying a j-link mini and trying to install Config Wizard, all in order to fix the setparameter() issue which seems to still persist on the BLCD Shield platform, 2 years after being first identified. 
my current roadblock is the downloading of the Config Wizard 1.x at https://infineoncommunity.com/2018Aug_GLOB_ATV_GATED_Config_Wizard_Id1003. I filled out the information and was emailed a link for downloading the software as well as other links. No link works. I would really like to get this working (with the ultimate goal, to run a motor using the BLDC Shield through an arduino. Any help would be appreciated.
